“…The vestibular apparatus may be thought of as the fine-tuning mechanism of balance control (Paulus et al, 1987) whose diminished function may compromise the effectiveness of visual and proprioceptive systems, acting singularily or cooperatively, to provide feedback for successful balance control. Some authors have shown vestibular function is clearly dysfunctional in Parkinsonism (Reichert et al, 1982;St-Cyr and Fender, 1969;Waterston et al, 1993), while others (Allum et al, 1988;Rascol, 1989;Pastor et al, 1993) report no dysfunction. Marsden (1982) suggested a host of factors, among them dysfunctional proprioceptive mechanisms, manifested by a delayed correction of false movements following perturbations, contributed to disturbances of equilibrium in persons with Parkinsonism.…”

“…All or some of these systems may be dysfunctional in persons with Parkinsonism (Bodis-Wollner, 1990;Marsden, 1982). Persons with Parkinsonism have an increased dependence on visual information (Cooke et al, 1978), and are unable to maintain balance when afferent visual cues become unreliable, conflicting with vestibular and proprioceptive input from other sensory systems, or when vision is absent (Bronstein et al, 1990;Waterston et al, 1993).…”

Lower extremity strength and joint range of motion, body sway, and electromyography responses have all been determined to be factors in balance control of healthy older individuals. The purpose of this study was to identify variables which effect balance control (equilibrium scores) of persons with Parkinsonism, and examine their relationships and predictive abilities. The composite equilibrium score from the sensory organization protocol of the Equitest was used as the dependent variable for the regression analysis. The independent variables included: 1) strategy score; 2) path sway during voluntary body displacement; 3) percent peak torque of knee flexion relative to that of knee extension (%PTKFKE); 4) peak torque of inversion of the ankle at (PTINV); 5) dorsiflexion ROM; and 6) medium loop latency (EMG). The model produced a significant overall relationship accounting for 88% of the variability in equilibrium scores. Positive and significant coefficients indicated a predicted increase in the equilibrium composite score with increases in the strategy score, PTINV and %PTKFKE. These results suggest that postural control of persons with Parkinsonism can be strongly predicted by these three variables.

“…Most often, instability is assessed by observing and rating balance performance during stance and gait tasks, such as the Get Up and Go test (from a seated position), the recovery to a push or pull at chest level (the retropulsion test) or self-paced walking [4,8,9]. However, qualitative assessment of these clinical tests does not provide accurate estimates of instability, does not correlate well with dynamic posturography results (because dynamic posturography usually only examines anterior-posterior instability www.elsevier.com/locate/gaitpost Gait & Posture 22 (2005) [240][241][242][243][244][245][246][247][248][249] during stance), and does not predict falls in daily life in PD [2,[10][11][12]. To overcome these limitations, an objective measure of postural instability in PD is needed which is applicable to both stance and gait tasks.…”

“…In addition, EPS can result from atypical antipsychotic medications 3) . EPS such as Parkinsonism, dystonia, and tardive dyskinesia cause postural control and voluntary movement disorders in psychiatric patients [4][5][6][7][8] . Psychiatric patients' ability to perform activities of daily living (ADL) is decreased because of postural control and voluntary movement disorders, and the quality of life (QOL) of inpatients is also decreased.…”

Abstract.[Purpose] Ability in activities of daily living of psychiatric patients is decreased because of postural control and voluntary movement disorders, and the quality of life of inpatients is also decreased. As preliminary research for evaluating standing balance of psychiatric patients, the purpose of this study was to investigate reach distance and movement strategy while subjects performed the functional reach test.[Subjects] Thirty-eight psychiatric patients and 38 healthy elderly control volunteers participated in this study.[Methods] Reach distance and movement strategy patterns were measured while subjects performed the functional reach test.[Results] The reach distance of the psychiatric patients was significantly shorter than that of the controls. The hip strategy was most often used by both patients and controls. Patients were more likely to select the ankle movement strategy than controls.[Conclusion] Based on the above findings, we speculate that the hip strategy is the ideal movement strategy for safely extending the reach distance of both psychiatric patients and controls. However, psychiatric patients were more likely to select the ankle movement strategy than controls.
